ReportViewer1.ServerReport.ReportServerCredentials这个属性需要一个接口实例。

ServerReport.ReportServerCredentials属性的类型为Microsoft.Reporting.WebForms.IReportServerCredentials,它可提供三种认证方式所需的证书(Credential):

 1) Form认证证书(GetFormsCredentials);

 2) 扮演认证证书(ImpersonationUser);

 3) 网络认证证书(NetworkCredentials). 

 当报表的服务器端使用网络认证时,需要实现NetworkCredentials接口,而且必须将GetFormsCredentials()接口的返回值设置为False,否则会导致论证失败.

　　那么我们如何实现呢，Code如下：

[Serializable]    public class CustomReportCredentials : IReportServerCredentials    {        private string _UserName;        private string _PassWord;        private string _DomainName;        /// 
        /// 自动从web.config中读取信息        /// 
        public CustomReportCredentials()        {            _UserName = ConfigHelper.Get("ReportViewerUser");            _PassWord = ConfigHelper.Get("ReportViewerPassWord");            _DomainName = ConfigHelper.Get("ReportViewerDomain");        }        /// 
        /// 手动指定认证信息        /// 
        ///         ///         ///         public CustomReportCredentials(string UserName, string PassWord, string DomainName)        {            _UserName = UserName;            _PassWord = PassWord;            _DomainName = DomainName;        }        public System.Security.Principal.WindowsIdentity ImpersonationUser        {            get            {                // Use the default Windows user.  Credentials will be                // provided by the NetworkCredentials property.                return null;            }        }        public ICredentials NetworkCredentials        {            get            {                // Read the user information from the Web.config file.                  // By reading the information on demand instead of                 // storing it, the credentials will not be stored in                 // session, reducing the vulnerable surface area to the                // Web.config file, which can be secured with an ACL.                //1.若没有指定用户名和密码时，默认为本地认证                if (string.IsNullOrEmpty(_UserName) || string.IsNullOrEmpty(_PassWord))                    return null;                else if (string.IsNullOrEmpty(_DomainName)) //2.若未指定域，则表示当前请求域                    return new NetworkCredential(_UserName, _PassWord);                else //3.用户+域认证                    return new NetworkCredential(_UserName, _PassWord, _DomainName);            }        }        public bool GetFormsCredentials(out System.Net.Cookie authCookie, out string user, out string password, out string authority)        {            authCookie = null;            user = password = authority = null;            // Not using form credentials            return false;        }    }

 

调用方法如下：

ReportViewer1.ProcessingMode=ProcessingMode.Remote; IReportServerCredentials irsc =newCustomReportCredentials("administrator","xxxxxx","xxxx"); ReportViewer1.ServerReport.ReportServerCredentials= irsc; ReportViewer1.ServerReport.ReportServerUrl=newUri("http://192.168.0.1/ReportServer/"); ReportViewer1.ServerReport.ReportPath="/test/report1";
